Question

1. Add an import statement above the class declaration to make the Scanner class available to your program.

Answer 1

Answer:

import java.util.Scanner;

public class Assignment{

public static void main(String [] args)

{

Scanner input = new Scanner(System.in);

String firstName, lastName;

System.out.print("Firstname: ");

firstName = input.nextLine();

System.out.print("Lastname: ");

lastName = input.nextLine();

String fullName = firstName +" "+lastName;

System.out.print(fullName);

}

}

Explanation:

I'll use the line numbers in the question to point at the corresponding instruction

import java.util.Scanner; -- The import statement (1)

public class Assignment{

public static void main(String [] args)

{

Scanner input = new Scanner(System.in); -- Scanner object (2)

String firstName, lastName; -- Variable declarations

System.out.print("Firstname: "); ---- Prompt to enter first name (3)

firstName = input.nextLine(); --- User input for firstName (4)

System.out.print("Lastname: "); ---- Prompt to enter first name (5)

lastName = input.nextLine(); --- User input for lastName (6)

String fullName = firstName +" "+lastName; --- concatenating both user inputs (7)

System.out.print(fullName); --- Print out fullName (8)

}

}
